Abstract

An optical disk apparatus includes a main chassis and a sub-chassis provided on a drawer, and has a skew adjusting mechanism of the main chassis and the sub-chassis which is skew-adjusted with reference to a rotational axis in tangential direction XT, which is parallel to a spot trajectory L of an optical pickup and located in the vicinity of the spot trajectory L, and a rotational axis in radial direction XR perpendicular to the rotational axis in tangential direction XT. This enables the skew adjustment in which a change in height of the optical pickup is small during the adjustment and distortion is small.

Description

technical field [0001] The present invention relates to an optical disc device, in particular to an optical disc device with a main chassis and a sub-chassis deflection adjustment mechanism. The main chassis and the sub-chassis store an optical pick-up mechanism and an optical disc motor. Background technique [0002] While optical disc devices are becoming more and more popular, miniaturization and high performance are recently required for the optical disc device as a whole. Therefore, mechanically high precision is also required in the structure of the optical disc device. For example, compatibility between miniaturization and high precision is desired in a skew adjustment mechanism of a main chassis and a sub-chassis which store an optical pickup mechanism and a disc motor. [0003] In Japanese Patent Application Laid-Open No. 2001-60323, a skew adjustment mechanism between the main chassis and sub-chassis is disclosed, wherein the skew adjustment is referenced to one r...
